How Search Engines Work
The first basic reality you need to know to learn Search engine optimization is that search engines usually are not humans. While this might be obvious for everybody, the actual differences between how humans and search engines view web pages are not same. Unlike humans, engines like google are text-driven. Although technology advances rapidly, search engines are far from smart creatures that can notice the beauty of a cool design or enjoy the seems and movement in movies. Instead, search engines like google crawl the Web, looking at particular site products (mainly text) to obtain an idea what a website is about. This short explanation is not the many precise because as we will see next, search engines carry out several activities to be able to deliver search results : crawling, indexing, processing, calculating relevancy, as well as retrieving.
First, search engines crawl the Web to see what is there. This task is performed by a piece of software, called a crawler or a spider (or Googlebot, as is the case with Google). Spiders follow links from one page to another and index everything they find on their way. Having in mind the number of pages on the Web (over 20 billion), it is impossible for a spider to visit a site daily just to see if a new page has appeared or if an existing page has been modified, sometimes crawlers may not end up visiting your site for a month or two.
